Abstract

The Canadian Water Quality Indices (CWQI) of the two monitoring stations on Rushikulya river system are calculated. For the CWQI evaluation, four critical variables such as pH, DO, BOD and TC are taken into considerations. Based on the CWQI values, the water quality of the monitoring stations are ranked into different categories. The CWQI score at Madhopur calculated using pH, DO, BOD and TC parameters as the variables revealed that water quality remained within Marginal-Good category. Whereas, CWQI score at Potagada calculated using EC, SAR (calculated from calcium, magnesium, sodium and potassium), chloride, sulfate, TDS and boron as the variables and comparing them with the respective tolerance limits for irrigation water quality, revealed that water quality remained at Poor category (CWQI Score: 14.94–27.24). The water quality deterioration at Potagada is mainly due to tidal effect.
